The influence of vision on spatial hearing of hearing-impaired and aided hearing-impaired listeners

Thirsa Huisman

As a side effect of improving speech intelligibility, many hearing-aid processing algorithms degrade the acoustic spatial cues, thereby reducing the ability of aided hearing-impaired people to localize sound sources. Ironically, this ability to locate sound sources allows normal-hearing listeners to separate a target of interest within a complex acoustic environment, thus aiding speech intelligibility. However, localizing sound sources does not rely solely on acoustic spatial cues; it relies on both acoustic and visual cues. Thus, hearing-impaired listeners may rely more on visual cues to compensate for their degraded acoustic spatial cues. This PhD project aims to investigate the influence of vision on sound localization, especially for hearing-impaired and aided hearing-impaired listeners, potentially allowing manufacturers and clinicians to better balance the trade-offs of different algorithms

This project will be carried out in collaboration with GN ReSound.
